Try ?&vp_lfilter. . or is it &?vp_lfilter. ?

>I am creating a view from a table and wanting to use macro substitution for the last view parameter. I've done this VFP6, but having a problem with VFP9. I am using VFEGenview to create the view. I get an error that I have a missing operand upon saving the view. I don't see the problem, does anyone else? The specific view parameter I'm having a problem with is &vp_lfilter.
